Description:

This demonstration multimeter has been developed
especially for teaching, and it can display the fol-
lowing quantities: Voltage, Current, Resistance,
Frequency, Temperature, Pressure and Acidity (pH).

The demonstration multimeter is supplied with a lar-
ge 4-digit display with 45 mm high illuminated digits
on the front panel. On the rear a smaller display with
14 mm high digits is provided for the teacher.

The connections for measuring Voltage, Current, Re-
sistance and Frequency are made with standard 4
mm safety jacks on the front panel. The temperatu-
re measurement is made using a type K thermo -
couple probe via the special connector designed for

this purpose. The Acidity (pH) measurement is per-
formed using a standard pH-electrode with a BNC
connector. Pressure measurements are made using
pressure sensor accessories. For thermocouple pro-
bes, pH-electrodes and pressure sensors, please
see the section on accessories.

The quantity to be measured is selected using the
rotary switch in the center of the front panel below
the display.

The instrument is supplied with an RS232 computer
interface for transferring data to a PC. This data
transfer can be performed using general communi-
cation software like hyperterminal – or the free pro-
gram Datalyse (datalyse.dk).
